But, have you ever thought that you probably want to know what actually living 1000m under the sea. Without going to the sea directly. Fortunately, in here we will give you the most interesting information about 12 most dangerous Animals in The Ocean Biome.

1. Great White Sharks

Often you watch shark from the movie. They eat everybody and not let the humans live in their territorials. But, as the matter of facts. You can say what the movie are actually talking about is true. Great White Shark of commonly called by “Great White” has already been the most dangerous and avoid creatures in the sea even for the sailor. They were called as the most bloodthirsty animal in the sea. This fact has been told in generations before the centuries.

White Shark or in the Latin name we can call them (Carcharodon carcharias). These animals commonly lived in sub-tropical oceans in both the northern and southern hemispheres.

White Shark often grows around 15 feet long; however, some of them even can grow bigger and probably more than 20 feet in length. When they were born they already have 4 feet long. They were born in a dozen with their siblings and immediately go towards its mother the minute after they were born. But, even they mother will also look at them as a prey to be eaten. The size of this shark can be the same as a school bus and average weight around 5.000 pounds. This made them as the largest predatory fish on earth.

Not only from their size and weight. They were called the most dangerous not for nothing. White shark can travel in a very incredible distance – more than 3000 kilometers in a month. They can swim from Tasmania to New Zealand within three weeks. They swim around 3-4 km/hour, the cruising range of a White Shark is slightly slower than the Olympic swimmers, but they can keep swimming for more than 100km throughout the day, and every single day. And when they were hunting the prey they can reach 55 km/hr for a short trip.

White shark can dive into 1.2 kilometers, where the water pressure is 120 higher than the normal ocean level. Average temperature they can swim is around 2 degrees Celcius and 27 degrees for the warm temperature.

White sharks show their teeth and roll their eyes towards the head when they attack their prey. Both movements put their jaw and teeth as the best attacking position. In the same time, they protect their eyes-a very useful thing when they prey. They commonly eat seals or stingrays, those animals have claws or thorns are vulnerable to fight back.

Who knows how shark reproduce? Were they hatching eggs? or Were they gave birth the same way whale gave birth? Alright, Great White sharks are ovoviviparous. In the other words, a shark grows inside an egg but they hatched inside their mother. Afterward, the shark pup is born. Pup is how we called shark baby. While they are still inside their mother womb, the shark pup will feed on the unfertilized eggs in order to grow. This feeding method is called as oophagy. The pregnancy period commonly takes about 12-18 months.

This period of time is actually longer than we expected or used to. When they are born, the average of their length is around 1.5 meters (5feet) and around 35 kilograms (77 pounds). Males will reach their maturity around 9 or 10, while the female sharks mature a bit longer which around 14-16 years. Scientists believed that white sharks can live until 30 years. But, need to remember that White Shark reproductions only happen in a very short timeframe. Because of the long pregnancy period, it is possible that female sharks will give birth every year. But, they need to take some time to rest after mating.

2. Sea Snake

Do you ever think that snake actually can swim? all snake can swim. Especially sea snakes they are not only slithery but also very dangerous. They love mostly in the water and very hidden. They sometimes come up to find air but they mostly spend their time under the water within hours. Yup, they can hold their breath that long.

Mostly they also live in the reef off the coast of Australia. They eat fish, eels, and fish eggs. They usually live under rocks and reefs you might not see them directly by your naked eyes.

Sea Snakes are cold-blood reptiles. Unlike the other snakes, they spend most of the time underwater and take a couple of minutes to the sea surface to take some air. Their lungs facilitate them to hold the oxygen up to two hours before they come to the surface to take another air. There are about 60 different types of sea snakes. And around 30-50 types belong to the Cobra family.

They normally found in shallows water of the Indian Ocean, and warm areas of Pacific Ocean. By the way, this Pacific Ocean also includes Indonesia. Mostly they also live in the reef off the coast of Australia. They eat fish, eels, and fish eggs. They usually live under rocks and reefs you might not see them directly by your naked eyes.

There are about 30-50 different types of sea snakes and they belong to the Cobra family. Sea snakes commonly grow until 2 meters long and have a small head. Their tails are flattened. These tails made them swim as fast as possible and flaps over their nostrils when close when they are under water. Sea snakes can grow about 0.5 meters long in average. But, some of the documentaries found cases of the sea snakes that can reach up almost 4 meters in length.

Snakes are dangerous. Because they are incredibly poisonous. One single venom can kill 8 people at once. But, for you who like to dive. Is one of the benefits to using the diver’s suit because they cannot get their fangs through the suit easily. They’re unlikely to attack humans unless they are being bothered.

The reproductions of the sea snakes are seemingly the same with the other snakes and lizards. The male snakes have two penises. But, only one that will be used during mating. And each one of them functions differently. Mating will take place underwater and sea snakes need to go to the surface to take some air during the process. The female controls breathing and she swims to the surface with the male is pulled along attached by the hemipenis. At the surface, the male takes some air and he has to wait till the next time the female comes up to breath. Males are unable to disengage until the mating process is finished.

Sea snakes give birth after pregnancy periods that takes Average time around four to eleven months, depends on what species are they? Most of the species will reproduce every year. All species will have their own mating cycle. Not only species that would differentiate their mating cycle. The geographical locations will also affect their mating cycle. Young sea snakes have to be independent once they were born. They will immediately swim to the surface to take some oxygen to breathe. In sea snakes life, there will be no parental care.

This 10 centimeters of octopus is the cousin of the squid. Their special thing is their ring blue color. Its stink can be deadly for an adult man. Their best weapon is their skin. It can make itself invisible. It adapts on the bottom colors and appearance. Sometimes it changed its color that you can see it. Its rings color is a contrasted and increased by the mixing black and electric blue in their almost white skin. Their appearance actually a visual warning. No predator would dare to bother this octopus.

This octopus will release a deadly neurotoxin that called Tetrodotoxin. This toxic will released once you are getting in touch with the octopus and enter inside your body. Tetrodotoxin will primarily make you paralyzed. And the victims will have blood symptoms within a minute. This will make you lack of oxygen to the brain.

The octopus reproduces like many other octopuses. Once the octopus reaches their adulthood, it usually has the urge to find their mate and do the mating process. The male gets attracted by the female and caressing her with the modified arm. This arms will be uses for mating. This arm called hectocotylus, which modified to transfer the sperm into the female. This arm will insert into the oviduct of the female and release little packets of sperm which slide down into the oviduct.

The female keeps the sperm until she lays her eggs. After that, the female will take care the eggs until they hatch. Once they hatch, the mother and father normally will die shortly afterward. The baby octopus will grow rapidly and increases its body weight by 5% each day. They normally live only three until five years.

4. Tiger Shark

Tiger Shark is one of the most feared and dangerous sharks. This shark was called as Tiger because they have vertical stripes on its body. It is going to be disappeared as they grow but it will stay there.

It belongs to the order Carcharhiniformes, the Carcharhinidae family, and the genus Galeocerdo. In addition, this shark is an elusive predator. Found throughout the world’s tropical oceans, he is one of the kinds of the ocean. These large blunt-nosed predators known as human-eaters.

Tiger sharks are named for the dark vertical stripes found mainly in the juveniles Tiger Shark. But as they growing up, the stripes begin to fade and disappear. Tiger sharks commonly live in the tropical and sub-tropical ocean. Large sharks can grow 6 to 7.5 meters in length and weigh more than 900 kilograms.

These sharks can travel as much as 80 kilometers 50 miles in a day stopping only to feed. Normally solitary and nomadic one event that brings them together in numbers is the turtle nesting and some females are arriving already.

They have sharp and powerful jaws that aim to crack the shells of the sea turtles and clams. They also eat sea snakes, seals, birds, squids, and sometimes license plates and old tires. Although they have an excellent eyesight, Tiger sense of smell can detect blood from the water within 2 kilometers.

But, currently they population become very low because of human activities. Their fins, skin, flesh and their livers contain high levels of Vitamin A. This means their body contains a great amount of vitamin oil. This vitamin oil makes human will always haunt them to be killed and sell.

5. Stingrays

For over a hundred million years. A stingray has roamed the oceans and almost a mythological animal. Extraordinarily graceful and considered potentially lethal.

Though not aggressive, the Stingray is equipped with a fearsome means of defense a venomous find found near the base of it powerful whip-like tail. A large ring can drive a spine into a wooden boat or deliver extremely serious painful wound. The most dangerous part of stingrays is its tail. Some of the stingrays have venom that can be fatal if found in human. There were already many human death cases because of the stingrays.

Small Description

The Stingray normally spend most of the day buried in the sand or floating in the oceans. They line camouflage as sand. They move slowly foraging for invertebrates hidden on the ocean floors. Because the stingray’s eyes are on top of their head and its mouth and nostrils bellow, it can actually see what they are eating. They can grow around 2meters; and more than 362 kilos.

Like sharks, the stingray has electrical sensors around its mouth that help them to sense their prey. When they sense the prey is nearby, they will use their mouths to catch them. Their teeth were designed to crash oysters, clams, and mussels.

Reproductions

Like the Shark, Stingrays also an ovoviviparous. Their period of mating is around winter and spring. Males have this electro sense to locate the smells of the females that are ready to mate. Females commonly used some special scents to let the males know that she’s ready to mate. To transfer its sperm, the male will use clasper that modified pelvic fins. The eggs will hatch inside the female. The young stingrays were born without any placenta. After they were born, they were independent enough to protect and defend themselves from the predators.
